WebApr 12, 2024 · Time Complexity: O(N 2), As we visit every node just once and our helper method also takes O(N) time, so overall time complexity becomes O(N) * O(N) = O(N 2) Auxiliary Space: O(H), Where H is the height of the binary tree, and the extra space is used due to the function call stack. Approach (Efficient): The idea is to write a utility helper … WebSuppose we are using the function int treeHeight (TreeNode root). If the tree is empty or tree has only one node, we return 0. This would be our base case. Otherwise, we traverse the tree in a post-order fashion and call the same function for the left and right child to calculate the height of the left and right sub-tree.
